I am getting a similar error I am using matlab version R2023a |

Can you try to open terminal inside of your nvim session (enter |

I have tried to reproduce your issue on my system (native Linux), but I couldn't. Could you start with a clean repo once again? This is what I'm doing to have this language server working: |
I have try above and even clone a clean master source, but it still failed and get same error. |
|
I'm using the same node version and npm 10.2.4. Which Matlab version are you running? Currently, I'm on R2022b. |
I switched the npm version to 10.2.4 and tested matlab R2022b R2023b R2024a, and neovim-nightly version, but they all failed! |

Hello, I"m using neovim nightly v0.9.5 via WSL 2 on Arch Linux. I have gone through most of the issues above, but have been able to resolve most by installing Matlab locally in the Linux WSL. I can see from the logs that the server goes up, and it connects to it after I open a matlab file. The issue I have is that a few seconds later I get a message that the client quit:
and the lsp.log file contains a very large output, but the top of the error there is [ERROR][2024-02-15 11:31:46] .../vim/lsp/rpc.lua:734 "rpc" "/home/rln/.local/share/nvim/mason/bin/matlab-language-server" "stderr" '),function(e){e.fromPlainText=function(e){return e.replace(/[\\`*_{}\ --- output truncated :LspInfo looks healthy enough for me I should add I tested Matlab R2021b and R2023b. Both have the same behavior. Any suggestions on how to do next to fix this? thanks! |
I was able to get this going on my side by using mason-lspconfig, installing matlab locally on my wsl linux install, and executing neovim disabling the proxies (I'm using a corporate laptop) using the alias mvim='(unset http_proxy && unset https_proxy && nvim)' my config (using lazyvim) looks like this. This could probably be cleaner, but this is working for me. I'm no expert on this, unfortunately, but just posting what I did that got things going for me. I also installed matlab_ls via Mason manually, but could've probably added it to the config below. {

I encountered this error too.

Can you try launching the desired MATLAB normally, run the If these do match and still does not work, can you share the value? |

Hey @dklilley, I did as you asked and opened my R2024a installation, ran require('mason-lspconfig').setup({
ensure_installed = {
'rust_analyzer',
'clangd',
'pylsp',
'texlab',
'lua_ls',
'matlab_ls',
},
handlers = {
lsp.default_setup,
matlab_ls = function()
require('lspconfig').matlab_ls.setup({
capabilities = require('cmp_nvim_lsp').default_capabilities(),
settings = {
matlab = {
installPath = '/home/jlock/MATLAB/R2024a',
},
},
root_dir = function(fname)
return require('lspconfig.util').find_git_ancestor(fname)
end,
single_file_support = true,
})
end,
lua_ls = function()
require('lspconfig').lua_ls.setup({
settings = {
Lua = {
diagnostics = {
-- Get the language server to recognize the `vim` global
globals = { 'vim' }
}
}
}
})
end,
pylsp = function()
require('lspconfig').pylsp.setup({})
end
},
})

The installPath should work, but I'm not very familiar with the Neovim setup. @tiagovla , do you have any ideas on this? |
